Tabula rasa 佩尔特．阿尔沃 总谱 环球版

一乐章 "Con moto"（乐章）的灵感来源于巴洛克时期的大协奏曲--一小群乐器（此处为两把小提琴）与乐队其他乐器的对抗--该乐章采用静态节奏和同音结构，具有维瓦尔第式的质感。预制钢琴--将不同的物体放入钢琴中，从而产生不同的椋鸟声（在这首乐曲中，螺丝钉位于弦乐之间）--明显是对钟声的借鉴。第一乐章由两个不同的片段并列展开：一个节奏活跃，一个平静，只有一把小提琴和一架钢琴参与其中。活跃部分的乐章在音域和节奏上逐渐增强，并在一个琶音丰富、近乎激烈的部分达到高潮。在第二乐章 "Senza moto"（无乐章）中，备奏钢琴的作用更为重要，它提供了唯一的节奏和色彩对比，在扩展的卡农乐段中，大提琴向上和向下扩展二度音阶，这与《大合唱》中使用的技巧类似，第一小提琴在卡农乐段中紧随其后。Per F. Broman 1997（摘自 BIS CD 834 小册子）

原文简介:
Inspired by the concerto grosso from the Baroque period - a small group of instruments, in this case two violins, against the rest of the orchestra - the first movement, Con moto (with movement), features Vivaldi-like textures resulting from its use of static rhythms and homophonic structure. The prepared piano - in which different objects are put into the instrument, thus creating different starling sounds (in this piece screws between the strings) - makes a clear reference to bells. The first movement develops through a juxtaposition of two different episodes: one rhythmically active and one calm section in which only one violin and piano take part. The motion in the active section increases gradually in register and rhythmic activity and culminates in an extensively arpeggiated, almost violent, section. In the second movement, Senza moto (without movement), the prepared piano serves an even more important function - providing the only rhythmic and coloristic contrasts to be extended canon sections in which the celli expand a diatonic scale upwards and downwards, similar to the technique used in Cantus, followed in canon by the first violins. Per F. Broman 1997 (taken from the booklet of BIS CD 834)

Preparation of the Piano: Metal screws of 5 or 6 mm diameter should be used. The screws should each be placed behind the dampers. Division of the strings into octaves by the screws is not necessary. In order to prepare the strings, they should be carefully separated by a felt wedge before the screws are inserted or removed, in order to avoid damage to the strings. Via the preparation, one of the three strings always vibrates freely, thus determining the pitch. The two strings prepared with the screw produce an alienated tone colour effect. As large a concert grand should be used as possible (not an upright piano). To achieve the desired tone colour, it is essential that the piano is prepared, and amplified.
